As shown in fig. 1, the discharging mechanism 1 releases the yarn to be sized, and the yarn is conveyed to the yarn cleaning mechanism 3 through the guide wire mechanism 2 to be cleaned, so that dust and hairiness on the yarn are removed, and the phenomenon that slurry adheres to the dust and the hairiness during sizing to increase the feeding resistance of the yarn is avoided, thereby reducing the yarn breakage risk in the subsequent sizing process. The yarn after cleaning treatment is sequentially sent to a sizing mechanism 4 for sizing, and is sent to a drying mechanism 6 for drying treatment, and finally is sent to a winding mechanism 9 for winding under the action of a wire guide mechanism 2. In the process, the broken line detection mechanism 7 detects the broken line condition between every two mechanisms in real time, so that the position of the broken line can be determined quickly. After the broken wire detection mechanism 7 detects the broken wire, the wire clamping mechanisms 8 on the two sides of the broken wire quickly react to respectively clamp the ends of the broken wire so as to quickly perform joint processing on the broken wire in the following process.

The PLC control technology is the prior art and is not described in detail. In addition, in this embodiment, the material discharging mechanism 1 and the winding mechanism 9 are the same as those in the prior art, and include a frame body and a shaft horizontally disposed along a direction perpendicular to a yarn feeding direction, and the wire guiding mechanism 2 includes a wire guiding frame and a wire guiding shaft disposed on the wire guiding frame, and are also the same as those in the prior art, and the material discharging mechanism 1, the winding mechanism 9 and the wire guiding mechanism 2 are not innovative points of the present invention, and are not described in detail.

The specific structures of the yarn breakage detection mechanism 7, the yarn clamping mechanism 8, the yarn cleaning mechanism 3, the sizing mechanism 4, and the drying mechanism 6 are described in detail in the following order along the yarn feeding direction.

The working principle and the using method of the invention are as follows:

clearing yarns:on water in the storage water tank 32 permeates the cleaning sponge 34 through the drainage cotton column 341 for the cleaning sponge 34 is moist, and the liquid level in the aqua storage tank 35 is higher than the lower terminal surface of sponge cover 371, and sponge cover 371 absorbs water and wets, and the yarn passes through from the level between cleaning sponge 34 and the sponge cover 371, and cleaning motor 372 drive cleaning roller 37 drives sponge cover 371 and rotates, utilizes moist cleaning sponge 34 and sponge cover 371 to clean the yarn. Therefore, the cleaning of dust, hairiness and the like on the surface of the yarn can be realized, the surface of the yarn is wetted in advance, the wetted yarn is easier to quickly size than dry yarn, the adhesive strength of the size is high, the subsequent sizing mechanism 4 can well size the yarn without using too much size, and the waste and the dripping of the size are reduced.

Sizing:a plurality of yarns pass through the corresponding sizing holes 44 on the sizing plate 43 one by one, the sizing valves 4531 on the sizing branch pipes 453 are opened, the sizing agent of the sizing tank 45 is sprayed onto the yarns in the sizing holes 44 from the sizing holes 441 on the inner side wall of each sizing hole 44 through the sizing pipe 452, the sizing branch pipes 453 and the pressurizing spray head 4532, the sizing of the yarns is realized, and the redundant sizing agent falls into the sizing tank 41 below the sizing plate 43. The sizing method adopting the pressurized spraying does not need to adopt a sizing roller, on one hand, yarns do not need to pass through the sizing liquid to be conveyed forwards, and the forward feeding in the sizing process of the yarns is effectively reducedResistance, thereby reducing the risk of yarn breakage; on the other hand, the yarn is not pressed into the slurry in the sizing tank 41 by the sizing roller, and even if the yarn is broken during sizing, the connection processing of the broken yarn joint is facilitated. Wherein, every sizing aperture 44 inside wall circumference array sets up four at least openings towards the whitewashing hole 441 of sizing aperture 44 axis, carries out the whitewashing to the yarn from a plurality of angles like this, guarantees the complete sizing of yarn surface ability to guarantee the starching effect of yarn.

Cleaning the pulp:in a normal state, the cleaning slurry rolling brush 53 is positioned on one side of the sizing plate 43 and above the sizing hole 44, so that the cleaning slurry component 5 is prevented from influencing the normal feeding of the yarn which penetrates out of the sizing hole 44. When the upper pulp hole 44 needs to be cleaned, the vertical cylinder 521 drives the whole pulp cleaning bracket to move downwards, so that the plurality of pulp cleaning rolling brushes 53 are coaxial with the corresponding upper pulp hole 44; then the horizontal cylinder 511 drives the cleaning plate 51 to move towards the direction close to the sizing plate 43 along the cleaning bracket, so that a plurality of cleaning rolling brushes are inserted into the corresponding sizing holes 44 one by one; finally, the slurry cleaning motor 533 drives the slurry cleaning rolling brushes 53 to rotate and position on the slurry cleaning plate 51, so that the inner wall of the sizing hole 44 is scrubbed and cleaned, and the slurry cleaning plate 51 and the slurry cleaning support are integrally reset after cleaning is completed.

Drying and breaking traction:the yarn passes between the upper clamp 6423 and the lower clamp 6422, in the yarn inlet 611, the feed gap, and the yarn outlet 612 in sequence. The yarn is dried by the upper drying cylinder 621 and the lower drying cylinder 622, and the yarn is located in the drying box 61, so that heat loss is avoided, and the drying effect of the sized yarn is ensured. When the yarn is broken in the drying box 61 and the broken yarn detection mechanisms 7 at the two ends of the yarn detect the broken yarn, the electromagnet 6427 at the broken yarn position is controlled to be electrified through communication, the upper clamping plate 6423 and the lower clamping plate 6422 are attached to each other under the suction effect of the electromagnet 6427 and overcome the tension of the tension spring 6426, and the broken yarn is clamped by the upper clamping plate 6423 and the lower clamping plate 6422. Then the servo motor 67 works to drive the whole wire feeding rod 641 to slide from the outer side of one end of the drying box 61 to the outer side of the other end of the drying box 61 through the material passing gap 63, so that the wire clamping of the wire feeding clamping seat 642 and the sliding of the wire feeding rod are utilized to draw the end of the yarn through the drying box 61, and the end of the yarn clamped on the wire feeding clamping seat 642 is pulled on the outer side of the drying box 61The head is connected with the end of the yarn clamped by the other yarn clamping mechanism 8.
